Abstract (en)
A method for manufacturing a wearable article is provided with a capability to reduce a discrepancy between sealing areas on outward and homeward paths through which superposed parts of a continuous material are joined to each other. The method for manufacturing the wearable article includes: a superposing step of superposing a first part (W1) and a second part (W2) of a continuous material (W) on each other; a conveying step of winding the continuous material (W) including the first part (W1) and the second part (W2) superposed on each other around a rotary drum (5) and conveying the continuous material (W); and a joining step of moving a movable part (10) of a sealer unit (7) outward and homeward in a cross direction crossing a conveyance direction in which the continuous material (W) is conveyed, while the continuous material (W) is conveyed by the rotary drum (5), to form liner sealing areas (S 1, S2) and thereby joining the first part (W1) and the second part (W2) to each other through the formed liner sealing areas in areas corresponding to both sides of the wearable article, and the method further includes, after the superposing step and before the joining step, a discrepancy reduction step of inhibiting a movement of the first part (W1) and the second part (W2) relative to each other by temporary fastening such as heat sealing at a place at which the first part (W1) and the second part (W2) are to be joined together.
